WATER-HEATER.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed July 1, 1907. Serial No. 381,692.

To all whom it may concern:

Be it known that 1, ROBERT FARREN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Water-Heaters, of which the following is a specification.

This invention is a hot water heater provided with a local or individual heating attachment designed for the use particularly of gaseous fuel, and having for its object to provide animproved and simple structure of the kind, characterized particularly by improvement with respect to the form and construction of the heater for the water which circulates through the radiator.

The invention is illustrated in the accompanying drawings, in which Figure 1 is an end elevation of a radiator provided with the invention. Fig. 2 is a similar elevation with the side plate of the heater removed. Fig. 3 is a side elevation. Fig. 1 is a top view. Fig. 5 is a detail of a relief valve. Fig. '6 is an elevation of a modification.

Referring specifically to the drawings, 6 indicates the radiator sections, connected together and supported in the usual or any convenient manner. The heating attach ment is located at one end of the radiator and has a pair of upright parallel tubes or headers 7, which are conveniently rectangular in cross section. These are connected at the top by a T-fitting 8 and at the bottom by a similar fitting 9 which have stems and couplings which tap the adjacent radiator section 6. Theheaders 7 are connected across by a series of inclined tubes 10. I11 one form the tubes are arranged in sets inclined in opposite directions from one header to the other. In the modified form shown in Fig. 6 the tubes are all inclined one way, and in this modification the top and bottom connections are closed at respectively opposite ends by plugs at 11. This gives a one way circulation which has some advantages.

The connecting tubes 10 occupy aportion of the len th of the headers, and located between the lower ends of the headers, under the tubes, is a burner 12 supplied. with gaseous fuel through a pipe 13.

The lower connection 9 has a bib cook 14 to empty the radiator when desired. The upper connection 8 has a relief valve indicated at 15, and shown in detail in Fig. 5.

This valve opens under pressure greater than that of its spring 16 and allows an outlet into the waste pipe 17, which may be connected to a waste main or arranged to discharge into a receptacle 18.

The headers 7 are flanged on the outer side or edge as indicated at 19, to receive a sliding cover plate 20 which may be removed or replaced by sliding the same up or down. This plate has holes 21 at the lower end to supply air to the burner.

The headers 7 are located closely beside the end. section 6 of the radiator, and the wall of said section forms one side wall of the passage for the hot air or products of combustion, the other side wall being formed by the plate 20. The end radiator section is thereby exposed to the heat of the burner and the water in such section is thus directly heated,

thereby utilizing to a complete extent the heat generated and serving to assist the tubular heater in maintaining the heated con dition of the water. The sliding cover 21 allows convenient access for inspection or repairs.

With the apparatus shown, having the relief valve 15, no expansion tank is necessary. The radiator is first filled with water, to the circulating line, that is, above the upper connection 8. When the water is heated sufiiciently to cause an-expansion beyond the capacity of the radiator the excess is forced out through the relief valve. When the Water cools the valve closes and the contraction forms a vacuum. There is no evaporation, and consequently no necessity exists for replenishing the water, but it will work indefinitely at one filling, since the relief valve is placed at such a height above the circulating connection that said connection will always be covered. The vacuum formed by the water when cooled is filled again by the heated water, but not to the overflow point unless the temperature should be raised above the initial heating. Such action is carried on indefinitely and saves the time and trouble of replenishing the radiator with water. Also the escape of moisture which would collect upon windows and walls is avoided.

I claim:

1. The combination with a radiator having an upright radiating section, of a water heating attachment connected thereto for circulation of the heating fluid. and. having a pair of spaced upright headers extending closely beside the radiator section, said headers forrn- I ing the end Walls and said section forming one side Wall of the heat chamber, a plate secured to the headers and forming the other side Wall thereof, tubes extending across said chamber, between the headers, and a burner under said tubes.

2, The combination With a radiator having upright sections, of a Water heating attachment connected thereto for circulation of the heating fluid and having a pair of spaced upright headers standing beside one of said sections, With a heating chamber therebetween,

- one Wall of the heating chamber being formed by the section, and a removable plate forming the other Wall of the chamber and connected at opposite edges to the headers.

3. The combination With a radiator, of a Water heating attachment connected thereto for circulation of the heating fluid and hav ing a pair of spaced headers With vertical flanges along the same, said headers standing upright beside the radiator which forms one Wall of the heating chamber, and a plate forming the other Wall of the chamber and engaging the flanges and slidable up and down thereon.

In testimony whereof I do affiX my signature, in presence of two Witnesses.

ROBERT FARREN.
